Precomputed Illumination

Video captions: Open Render Settings and select the Raytracing Quality tab. Please select Precomputed Illumination as the illumination mode in Interactive. Activate Raytracing in the toolbar. As you can see, there is no change to the main look of the scene. In the mode, Precomputed Illumination, HDR is still set as basic lighting. Besides, ambient occlusion is also still used for shading. Now, real reflections and refractions of the scene are used. Open the Material Editor and change your default environment to Is Visible. You can now see the default material on the sky dome geometry used in your scene. Open the Scenegraph and hide the sky dome geometry. All the specular mirrorings in the surrounding areas will disappear. This suggests you should work with a surrounding geometry in raytracing. When working with surrounding geometry, no interactive feedback is displayed. During the transformations of your objects, you can see an interactive update in specular mirrorings. Precomputed illumination is the fastest raytracing illumination mode within VRED.
